Payload State Prediction Based on Real-Time IoT Network Traffic Using Hierarchical Clustering with Iterative Optimization.

IoT (Internet of Things) networks are vulnerable to network viruses and botnets, while facing serious network security issues. The prediction of payload states in IoT networks can detect network attacks and achieve early warning and rapid response to prevent potential threats. Due to the instability and packet loss of communications between victim network nodes, the constructed protocol state machines of existing state prediction schemes are inaccurate.

An aggregation-induced emission fluorescent probe for highly sensitive and selective detection and imaging of Hg in living cells.

Mercury ions (Hg), as one of heavy transition metals (HTM), is a highly toxic metal that is hazardous to human health. Here an aggregation-induced emission (AIE) fluorescent probe is designed for the highly sensitive and selective detection of Hg. The probe is engineered with a tetraphenylethene (TPE) derivative as the fluorophore and thiopropionic acid as the site of recognition for Hg.

Anti-Asthma Effect of an Active Components Group from Decoction of and Its Chemical Composition Characterized by Liquid Chromatography-Quadrupole Time of Flight Mass Spectrometry.

The decoction of is used as a traditional medicine for treatment of asthma in China with a long clinical history. The aim of the study was to investigate the anti-asthma activities of an active components group obtained from the decoction of in histamine and ovalubumin induced asthma guinea pigs. The experimental asthma model was established with spray of histamine and ovalbumin (OVA) followed by intragastric administration of extract and fractions.

Enrichment and Cytotoxic Activity of Curcuminoids from Turmeric Using Macroporous Resins.

Curcuminoids are functional secondary metabolites abundant in turmeric. In the present study, a simple and efficient method for enrichment of curcuminoids from turmeric was developed using macroporous resin. Eight different types of macroporous resins were examined by static adsorption/desorption properties and the type of XDA-7 was selected as the optimum one.
